If one has a two-digit number, take it and add the two numbers together and put that sum in the middle, and one can get the answer. For example: 24 x 11 = 264 because 2 + 4 = 6 and the 6 is placed in between the 2 and the 4. Second example: 87 x 11 = 957 because 8 + 7 = 15 so the 5 goes in between the 8 and the 7 and the 1 is carried to the 8.
He is also the owner of world records for mentally calculating the 13th root of 100-digit numbers and 200-digit numbers. [ 2 ] On 10 May 2002, he calculated the 13th root of a 100-digit number in 13.55 seconds, beating the record held by Willem Klein (88.8 seconds) and the somewhat less official record of Gert Mittring (39 seconds).
The naming procedure for large numbers is based on taking the number n occurring in 10 3n+3 (short scale) or 10 6n (long scale) and concatenating Latin roots for its units, tens, and hundreds place, together with the suffix -illion. In this way, numbers up to 10 3·999+3 = 10 3000 (short scale) or 10 6·999 = 10 5994 (long scale

The above equations confirm that there is no Kaprekar constant for numbers with five or more digits. There are no Kaprekar numbers for 5-digit and 7-digit numbers because they do not satisfy the above equations (1)~(5). For six-digit numbers, there are two solutions that satisfy equations (1) and (2). [9]
